IMPROVEMENT IN CAPSTANS.

The Schedule referred to in these Letters Patent and making parl; of thesame l drawing.

My invent-ion relates to a capstan having two separate and independentspools or. barrels which revolve on -the same axle, but while operatedby the same power 'each can he adjusted to revolve at a different speed,or at the same speed, or one can be made stationary while the otherrevolves. Y

This is effected by' constructing; the capstan like those in generaluse, only that I extend the main or long axle far enough to receive onit a second for additional spool or barrel, which is placed immediatelyabove and on the first spool, and is at-tachable to it by pins. v

'lhef first spool, having pawls in its top edge, in which a ratchet,placed on the second one, works.

This second spool is also attachahle to the drum of the axle by means ofpins, all of which will he more l'ully seen by the following'description and reference to drawing, in which- -Figure l represents aview of' the complete capstan.

Irigare 2, an end view of the top end of t-he first or lower spool orbarrel.

Fignre', an end view of the lower end of the second or top spool orbarrel.

Figure 4, an end view of the top end of the same.

Figure 5, a top end view of the drum.

A is the supporting-flame of the capstan, which should he substantiallyconstructed. p

B, the main or long,r axle, on which the spools revolve. Y

C, its bevel-wheel, by which it is connected with the steam-power.

D, its spur-wheel, which connects with a like one, F, -on the counteraxle G.

H, a spur-wheel on axleG, which connects with a like one on the spool.

The dimensions of all of which may he as desired, and it is by the meansof these axles and wheels that motion is imparted to the spools and thepower militiplied.

I is the first or lower spool or barrel, which revolves on the main axleB, provided in its top end with the pawls J J J, 6to., and pin-holes KK, as shown in fig.

2, in which pawls a ratchet on the second or top spool works, and vinwhich pin-holes pins are inserted trom .nu L 2542/94 like ones in thetop one to connect them together when desired.

L is the second or top' spool or barrel, which also revolves on the axleB, and also provided with the pin-holes M M in itslower end, andratohets `N N, as

shown in tig. a.

These pin-holes are brought opposite those in thev lower spool, and pinsinserted when they are to he made fast toether.`

It `is also provided in its top endA with the pin-holes O O, as shown inigA, which are brought opposite to the pin-holes 'q q, fig. 5, in thedrum or head It, and pins inserted therein when it is desired to connectthe spool with the drum.v

S S S S represent pins inserted in holes.

.l, pawl-bedon top of frame A.

When it is desired to move both spools at the same speed bring thepin-holes K K M M in the respective spools I L and insert therein thepins S S, first having withdrawn the pins which connect the spool .Lwith the dru'm It. l

And when desired to' move the spools at different speeds withdraw'thepins S S from the holes K K M M in the respective spools I L, and bringthe pin-holes O O in the spool L, opposite to those q q in' the.drum-head R and insert the pins S S therein.

Io move one only, withdraw all the pins.

The drum-head It is made attachable to the axle B by a key in a key-seattherein, which must be made fast thereon, when desired to work bothspools independently.

'.'Ihe drum R is provided with lever sockets to admit of the top spoolbei'n'g worked by hand from that point.

The top end of the first spool has the same provision for the likepurpose.

Wha-t I claim as my invention, and desire to secure by LetterstPatent,is l 1. lhe spool or barrel L, provided with the pinholes M M O O, andratchets N N, arranged as and for the purpose herein described.l 4

2; The spool L, provided with theholes M M O O, ratchets N N, in.combination with the spool or barrel I, provided with the pin-holes K Kand pawls ,J-,J J, arranged as and for the purpose herein set forth.
